The netio230a is a software to control the Koukaam NETIO-230A, a cheap but advanced multiple socket. It is programmed in the scripting language Python. It is easy to use and you may use it in your own projects according to the terms of the GPL v3 as included in the notes of the code.

You can find more information on the Koukaam NETIO-230A on the wiki page Koukaam NETIO 230A.

If you are using Windows and are not that much into programming, then you might have a look at the very good C# project by Christoph Schaffhauser. It includes a reusable DLL as well as a GUI and the software is Freeware. The DLL is released in source code too.

this software's core

The core of this software is the Python netio230a:

• netio230a.py - The class netio230a with the functionality to query and command the Koukaam NETIO-230A

command line user interface

There is a command line tool (to switch on/off ports) included in the package:

• netio230a_ctrl.py

graphical user interface

And a graphical user interface is also included. PyGTK gui for the NETIO-230A (query status / switch on/off ports):

• netio230a_gui.py

You can find screenshots on the screenshots site of the project website.

examples to show how to use the netio230a module/class in your Python projects

To show you how you can take advantage of that class in your own scripts, there are also several example files included. Take a look:

• example.querySystemStatus.py Query all information of the NETIO-230A
• example.switchPower.py switch on/off a port of the device
• example.setTime.py manually set the time of the box
• example.interrupt.py interrupt an output for a predefined time
• example.querySystemStatus.py about 8 hours ago mostly changed examples [pklaus]
• example.reboot.py reboot the NETIO-230A (without loosing the power status on the ports)

discovery tool

There is also an automatic device discovery implemented in the class to trying to provide the same functionality as the Windows Tool NetioDiscover.exe by Koukaam. It is able to detect all Koukaam NETIO-230A devices on your network (must be on the same subnet as your computer is). What it cannot do is to set the IP of the device yet.

• discoverNETIOsOnLAN.py

example run:

$ python discoverNETIOsOnLAN.py
Trying to discover any Koukaam NETIO-230A available on your LAN
